This is""ac"con1`plished "by an" intervening driving mechanismso constructed `as to be the motor" but to` become inoperative `there-`after "and to` automatically resume its operativeconditionas soon as theniotor is 5de# energized sothat it will again function when the motorisonce more energized: Thisintervening `rnechanisin comprises anendless` one being inL the nature of a mounting or bearing and theother,`1nd1`cated by 4, being `'operati"ve"duringthe firstewrevfolutionsof i chain ridingaround sprocketwheels," the secured toashaftwhich is connectedf by ratchet `mechanism with the adjacent reelso that when the sprocket Wheel `4 isturned byimotor power in the onedirection it will `It'ighroilgh the ratchet device) fturn the reel 8inthe saine direction; this direction corresponding to the winding-updirection of the belt on the reel S.
